CISCO-ERR-DISABLE-MIB
AI MIB Summary
The CISCO-ERR-DISABLE-MIB enables SNMP-based configuration and monitoring of the Cisco error-disable mechanism, which automatically shuts down interfaces, VLANs, or Layer 2 ports upon detecting specific abnormal conditions such as BPDU guard violations, storm-control thresholds, UDLD failures, or port-security breaches. It provides visibility into the operational state of these disabled entities and manages the global parameters for automatic error recovery, including the enablement of the feature and the specific re-enablement timer intervals.
This MIB module provides the ability for a Network Management Station (NMS) to configure and monitor the error-disable feature via SNMP.
The error-disable feature allows other software features running in a system to operationally disable a system entity upon detecting abnormal conditions.
Examples of such a system entity include interfaces, a vlan configured in the system, or a VLAN allowed on specific layer 2 multi-vlan interface.
More specific examples:
a) When BPDU guard is enabled on an interface it is expected that no BPDU packets are received by the interface. If a BPDU packet is received, then the BPDU guard will operationally disable the interface.
b) Users can configure a particular threshold of broadcast packets received on an interface. If the number of packets received exceeds the threshold, then storm-control will disable the interface.
c) When unidirectional Link Detection (UDLD) detects a unidirectional link on an interface, it can disable the interface.
d) On a trunk or a multi-vlan layer 2 port, if port-security detects violation on a particular vlan, then it can operationally disable that vlan on that port.
The definition of 'abnormal condition' is under the control of features that make use of the error-disable feature to disable system entities.
The error-disable feature supports the following
configuration:
1) Whether software features can in fact use the error-disable feature upon detecting abnormal conditions.
NOTE: Some software features will ALWAYS use the
error-disable feature to disable entities upon detection of error.
2) Whether the system can attempt to automatically recover after a system entity has been disabled (e.g., A system can attempt to bring up a physical interface which had been disabled earlier)
3) If error recovery is possible, then the time interval to wait before the system starts the recovery attempt.

ciscoErrDisableMIBThis MIB module provides the ability for a Network
Management Station (NMS) to configure and monitor the
error-disable feature via SNMP.
The error-disable feature allows other software
features running in a system to operationally disable a
system entity upon detecting abnormal conditions.
Examples of such a system entity include interfaces, a
vlan configured in the system, or a VLAN allowed on
specific layer 2 multi-vlan interface.
More specific examples:
a) When BPDU guard is enabled on an interface
it is expected that no BPDU packets are received by
the interface. If a BPDU packet is received, then the
BPDU guard will operationally disable the
interface.
b) Users can configure a particular threshold of
broadcast packets received on an interface. If the
number of packets received exceeds the threshold, then
storm-control will disable the interface.
c) When unidirectional Link Detection (UDLD) detects a
unidirectional link on an interface, it can disable
the interface.
d) On a trunk or a multi-vlan layer 2 port, if
port-security detects violation on a particular vlan,
then it can operationally disable that vlan on that
port.
The definition of 'abnormal condition' is under the
control of features that make use of the error-disable
feature to disable system entities.
The error-disable feature supports the following
configuration:
1) Whether software features can in fact use the
error-disable feature upon detecting abnormal
conditions.
NOTE: Some software features will ALWAYS use the
error-disable feature to disable entities upon
detection of error.
2) Whether the system can attempt to automatically
recover after a system entity has been disabled (e.g.,
A system can attempt to bring up a physical interface
which had been disabled earlier)
3) If error recovery is possible, then the time
interval to wait before the system starts the recovery
attempt. MODULE-IDENTITY .1.3.6.1.4.1.9.9.548 |

cErrDisableIfStatusTableThis table provides interface (port) specific
error-disable status information. Each conceptual row
provides status information about a {interface, vlan}
disabled by a feature.
On a trunk or multi-vlan access interface, a given vlan on
the interface can be error-disabled. In this case, the row is
indexed by the ifIndex for the interface and the vlan
index corresponding to the vlan in question.
If the interface is carrying only 1 vlan or the entire
trunk interface is error-disabled (due to link flaps, for
example) then the vlan index portion of the row index is
0. SEQUENCE OF CErrDisableIfStatusEntry .1.3.6.1.4.1.9.9.548.1.3.1 |
